To all whom it may concern:

Be it known that we, Annonn Exam nat on and KARL MARX, subjects theformer of the King of Bavaria and the. latter of the Duke of Brunswick,residing the former at Schillerstrasse 5 and the latter, atAlbrechtstrasse 16, Dessau, Germany, our post-oflice addresses being theformer Schillerstrasse 5 and the latter Albrechtstrasse 16, Dessau,

Germany, have invented certain new and useful Improvements in New Dyesfor Furs,

' Hairs, and the like, of which the following is a specification. v

In a co-pending application, serially numbered 7 29,874, we havedescribed and claimed new dyes for furs, hairs and the like which'consists of or comprises anaromatic paradiamin of the general formula:

shorter time if a 'para-diamin and a meta' diamin are mixed together.

Now it has been found that one can obtain the present new dyes in a verystable form and most adapted for the present urpose as well as for thedyeing process w ich they are to be applied for. This effect is attainedby using both components that is on the one hand the respectivepara-diamin Y and on the other hand the respective metadiamin, in theform of a salt and more especially' in the form of a salt of aninorganic acid, such as for instance hydrochloric, acid, orsulfuric'acid. I v

Specification of Letters Patent. Patented June 22,1915. Applicationfiled April 25, 1914. Serial No. 884,459.

The following examples serve to illustrate our invention, the partsbeing by weight:

1. SOy parts' of para-aminodimethy anilin %sulfate v 4 2- 6 -M H8)Q-t ZQi) arethoroughly mixed with parts of metatliaminoanispl 1} sulfate ornnssAu, GERMANY, AssIqnons 'ro'AcrInn mnmxnrron, or Bnanm, GERMANY.

in order to obtain a hdmogeneous mass. In

dyeing a fur, being previously niordanted or not, the new dye is to bedissolved in water and the calculated quantity of an inorganic base,such as ammonium hydroxid, is to be added in order to produce the freebases from the components of the newdye;

it is convenient to state that such a solution in order to serve as'adyebath must also contain further quantities of a suitable base and moreespecially of ammonium hydroxid and must also contain a suitableoxidizing agent, such as hydrogen peroxid. In this Way there is obtainedfor'ins'tance on a fur and more especially on a furmordanted withferrous sulfate a fine and deep blue black with a-full sight overhand. Ir Accordin y asanother mixture of the two above-namegi substances amixture of parts of para aminodimthylanllm hydrochlorid and of 6Q partsof meta-diaminoamsol'sulfate may be given.

'2. In order to obtain a new dye according to the present inyention onemay also proceed as follows: 80 parts of para-aminomonoethylanilinsulfate areincorporated' with 50 arts of meta-diaminoanisol sulfateorder to perform the dyeing process with until a -omogeneous mass isobtained. In

this new dye one may proceed according to '9 the indications given inexam le 1; thus can be obtained 'on a fur mor anted with ferrou su atand u n e ia e P P tions of the dye an intense bl1 11Sh' black of agreat stability and of a full sight overhand.

It is obvious that our present mvention is not to the foregoirhexamples01' t0- the details given therein. us for nstance instead of a,para-aminodlmethylaml n sulfate or hydrophlorid apara-amlnodlethylanilin sulfate or hydrochlorld or instead ofpara-aminomonoethylanilin sulfate. ahydrochlorid thereof or a sulfate orhydrochlorid of para-aminomonomethylanilin may be employed as well as asalt of a derivative of these amins containing a substituent attached tothe benzene nucleus. Furthermore instead of meta-diaminoanisol sulfate ahydrochlorid of this base or a salt of meta-diaminophenetol may be used.

it is obvious that in preparing the new dyes according to our presentinvention from such diamins the proportions of the ingredients may bevaried in order to obtain the best results, the special mixture for anew dye depending of course to a great extent upon the desired shade aswell as upon the-special nature of the furs, hairs, etc., to

be dyed.
